Security Bulletin: Vulnerabilities in ntp affect Power Hardware Management Console (CVE-2015-1798 CVE-2015-1799 CVE-2015-3405)

Vulnerability Details

CVEID: CVE-2015-1798
DESCRIPTION: Network Time Protocol (NTP) Project NTP daemon (ntpd) could allow a remote attacker to bypass security restrictions, caused by the acceptance of packets that do not contain a message authentication code (MAC) as valid packets wen configured for symmetric key authentication. An attacker could exploit this vulnerability using man-in-the-middle techniques to bypass the authentication process.
CVSS Base Score: 5.4

CVEID: CVE-2015-1799
DESCRIPTION: Network Time Protocol (NTP) Project NTP daemon (ntpd) is vulnerable to a denial of service, caused by an error when using symmetric key authentication. By sending specially-crafted packets to both peering hosts, an attacker could exploit this vulnerability to prevent synchronization.
CVSS Base Score: 5.4

CVEID: CVE-2015-3405
DESCRIPTION: Network Time Protocol (NTP) could allow a remote attacker to conduct spoofing attacks, caused by the generation of MD5 symmetric keys on big-endian systems by the ntp-keygen utility. An attacker could exploit this vulnerability using the generated MD5 keys to spoof an NTP client or server.
